Abstract :
In power generation plants, irrigations, drainages and so on, we have needed the optimum designs of suction sumps in order to achieve low initial/running costs, compact size, high efficiency and high performance. In the present study, we attempt to reveal the unsteady three-dimensional flow structure in a suction sump with the vertical-wet-pit-pump configuration. Using the 3D-PTV (three-dimensional particle-tracking velocimetry) techniques, we investigate the concerning flow.
